Definition of Unearned Revenue in Accounting. Unearned revenue is the same thing as deferred revenue. In accounting, unearned revenue is a liability. It is a liability because even though a company has received payment from the customer, the money is potentially refundable and thus not yet recognized as revenue.
Since the company considers unearned revenue as a liability, it appears in the liabilities section of the balance sheet. When the company delivers all or a portion of the product or service to the customer, it reduces the balance owed to the customer. The amount earned through the delivery of the product or service represents earned income, which the company reports on the income statement. The remaining balance of unearned revenue appears on the balance sheet.
